A method is designed to adjust the distance between the central axes of two ocular lenses of an optical instrument. The method involves the use of a link mechanism to actuate two movable prisms and the two ocular lenses of the optical instrument to move respectively along a base surface such that the optical axes of effective diameters of the two movable prisms are coaxial with the optical axes of the corresponding ocular lenses.
